BRUSH-MAKING.

Specification of Letters Patent.

Patented May 4, 1915.

Application filed February 9, 1914. Serial No. 817,511.

T 0 all whom it may concern Be it known that I, ARTHUR EFRAIM SILANDER, a Finnlander, subject of the Czar of Russia, residing at 6 Gulmbacherstrasse, Berlin, W. 50, Germany, have invented new and useful Improvements in Brush-Making, of which the following is a specification.

The primary object of this invention has been to devise certain improvements in apparatus for making brushes the invention being designed with a special view of affording advantageous instrumentalities for facilitating the inserting of bristles or hairs into the head of a brush or broom.

The apparatus of this invention enables the holes of the head of the brush to be easily and completely filled with the bristles without making necessary the tapping of the bristles into the'holes.

Further, according to this invention parallel rods are arranged passing transversely through the bristle container, and means are provided for giving to and fro movement to the edges of the rods crossing the longitudinal axis of the container and supporting the bristles, so that the point of support of the bristles is changed so that they fall into the guiding passages either vertically, or approximately vertically.

Yet further, the invention comprises the arrangement of hoods above these rods in order to provide for adjustment of the interspace between the rods according to the length of the bristles.

Again, yet another feature of the invention consists of a carriage, the portion of which receiving the head of the brush and the mold device above referred to, is so adjustable up and down that in each position the head of the brush and the mold device both lie parallel to the bristle container.

Finally, the invention comprises a stripping device provided in front of the bristle container which strips off the superfluous bristles when the full brush head and mold device are drawn out of the machine.

Some embodiments of the present invention are illustrated in the accompanying drawings, in which Figure 1 is a vertical crosssection, and Fig. 2 a vertical longitudinal section of a machine embodying the invention. Fig. 3 is a fragmentary view of a portion of the bristle container seen toward the top of Fig. 1. Figs. 4 to 7 illustrate modifications of Fig. 3, while Fig. 8 illustrates diagrammatically the direction of the bristles in Vertical guiding slots 4 are formed in the These slots upper parts of the side walls. serve to guide the slides 5 during their upward and downward movements. The slides other end with an eccentric strap 8. These eccentric straps embrace eccentrics 9 which are keyed on to the ends of the shaft 3 projecting beyond the framing. The two slides 5 derive their up and down motion from the rotation of the shaft 3.v These two slides have two inwardly projecting ears 10. A. rectangular frame 11 is fastened on these cars and so takes part in theupward and downward movement of the two slides. This frame serves as a container for the bristles or hairs. Spiral springs 12 are fastened at one end to the edges of this frame and at the other end engage with pins 13 fixed upon the side walls 1. These springs have the function to draw the frame 11 and with it the slides 5 upward so that a motion is ob tained which is as free from shock as pos-' sible.

The lower part of the frame is made in the form of a funnel or hopper, ascan'be seen in Fig. 1, and is fitted with a number of longitudinal walls 14, which are spaced wider at the top than below, so that'small funnels are formed by these intermediate walls and are further divided by a cross wall 15.

The head 22 of the brush or broom, and the corresponding guiding or mold device, are arranged in'known manner belowthe container. A cross bar 16 is arranged on the inside of each side wall 1 below the bristle container for this purpose, and serves as a running surface for the carriage 18 running. upon rollers 17 Bolts 20 are screwed into suitable internally-threaded holes 19 on the.

sides of the carriage. These bolts are retatably' arranged in a frame or board21 the brush and the mold device. Sprocket wheels 23are fixed on the bolts 20 and over these wheels an endless chain 24 passes. By pulling this chain either to the right or to the left the sprocket wheels 23, and with them the bolts 20, are correspondingly rotated and by this means are screwed further into the holes 19 in the carriage or are unscrewed from these holes. In this way the position of the frame 21 relatively to the lower edge of thebristle container 11 can be adjusted. Also, by this means sufficient'adjustmento'f the mold device and head of the brush relatively to the bristle container is provided and it is possible to determine the most favorable,position for the mold device and head of the brush.

Arod 25Lis provided onthe front part of the carriage to serve as a handle for draw-- ing the carriage from below the bristle container 11 along the bars l6serving as rails in order to regulate the working of the machine and to replace the mold and brush head filled with bristles by empty ones. A comb" 26 isprovided on the front part of the machine and is so arranged that when the carriageis drawn out the bristles lying across the top of thebrush head are cleared ofl. A collecting receptacle 27 for catching the bristles which do not pass intothe head of the brush is provided below thecarriage.

Immediately above the funnels or hoppers in the bristle container rods 28 of oval cross section are rotatably mounted longitudinally. The 1st, 3rd, 5th, 7th and so on rods are connected together by means of a hinged rod 29. (see Figs. 1 and 3). This rod 29 projects from the frame 11 to the right of the bristle container and carries a roller 30 which is pressed by means of a spring bearing against the wall of the frame against acurved cam track 33 fixed on the frame of the machine by means of flanges 31. The 2nd,'4th, 6th, 8th and so on'rods 28 are connected together through a further hinged .rod 34, which similarly projects from the frame. 11 of the bristle container to the right and similarly carries a roller 35 which is pressed by means of a spring 36 against,

the cam track'33. I

During the upward movement of the bristle container 11 rods 29 and 84 are pressed inward by the cam track 33 sothat the rods 28'take up the position shown in Fig.3,- and upon the downward movement of the bristle container again return to the position shown in Fig. 1. By this means, as is evident without further explanation, the points of support ofthe bristles are changed and the bristles are caused to fall down into the funnels in a greater number. This is specially facilitated owing to the consequent rotation of the rods 28 toward one another.

It is possible to work with bristles in th is in the left hand illustration that with broad 8 channels the position of the bristles deviates considerably from the vertical and the bristles when brought up to the head of 7 the brush rest crosswise and stop further work. On the contrary, when narrower channels are used, asisshown-in the right hand diagram, the bristles take up a position deviating very little from the vertical.

As is shown in Figs. 4 and 5 vertical strips of sheet metal 37 maybe arranged above the funnels, alternate strips being hinged at the 7 lower extremity and be rockedbackward andforward by means of rod 38 (see Fig.

5). By this means also a change in the'point ofsupport of the bristles is brought about and the same are caused to fall more quickly into the funnel. Instead ofrocking the strips of metal'these can be pushed backward and forward in a simple manner as is illustrated in Fig. 6.

In order to enable short bristles to be used hoods 39 are'inserted above the rods 28 (see Fig. 5). These hoods are of a certain breadth at the top in order to cause the points of support of the bristles to ap proach one another more nearly. The rods 28 and '37 can also be mounted in the frame of the machine and can be driven in any desired manner so that they do not take part in the movement of the bristle container. 1
